Percent Yield Theoretical Yield Actual Yield Theoretical Yield The maximum amount of product that can be formed from given

amounts of reactants The amount you should get in a perfect world Use equation and stoichiometry to calculate this amount Actual Yield

The amount of product that actually forms when a reaction is carried out in the lab Percent Yield A measure of the efficiency of a

reaction carried out in the lab The ratio of the actual yield to the theoretical yield Percent yield = actual yield theoretical yield

x 100% Percent yield should not be greater than 100% Often less than 100% Rxns. dont always go to

completion Some product can be lost during filtering or transferring Reactants or products not measured carefully When 84.8 g of iron(III) oxide reacts with an

excess of carbon monoxide, iron is produced. Fe2O3(s) + 3CO(g) 2Fe(s) + 3CO2(g) What is the theoretical yield of iron? When 5.00 g of copper reacts with excess silver nitrate, silver metal and copper(II) nitrate are produced. What is the theoretical yield of

silver in this reaction? If 50.0 g of silicon dioxide is heated with an excess of carbon, 27.9 g of silicon carbide is produced. SiO2(g) + 3C(s) SiC(s) + 2CO(g) What is the percent yield of this reaction?

If 15.0 g of nitrogen reacts with 15.0 g of hydrogen, 10.5 g of ammonia is produced. What is the percent yield of this reaction?
